The project, from HOUSE's David Shore, follows a former cop, Vince, who trades it in to become a low-rent lawyer. The man uses his street-smarts and wit to manuever the legal system, fighting his own demons, and attempting to win back his ex-wife.

Grunberg takes on the role of 'Mark,' the older brother of Vince. According to the report, Mark is "developmentally disabled as a result of a childhood accident but high functioning. He works as the receptionist at his brother's law firm and believes Vince can save the world."
